InfoFrames & VSIF
InfoFrames are HDMI data packets that describe aspects of the active signal. VSIF is a Vendor Specific InfoFrame used for vendor-defined signalling.
InfoFrames are small data packets that travel in the HDMI signal next to the picture.
They work like a label on a parcel: they tell the TV what is inside, such as the colour format or whether it is HDR.
A VSIF is a special InfoFrame that a company or standard group defines for its own information.
Can the HDfury Vertex read and change InfoFrames and VSIF?
YESYes. It can capture, edit, block or replace HDR metadata, AVI and VSIF InfoFrames, and it reads SPD, Audio, HDMI Vendor and HDMI Forum InfoFrames (p.110).
How to use it with the Vertex:
- See the captured AVI and VSI in the AVI/VSI IF tab (p.34–35), the others in the DV/IF tab (p.36).
- OLED page 5 (IF info) shows InfoFrames on the unit (p.42).
- Send AVI / Send VSI replace them, Disable AVI / Disable VSI block them; advanced users only (p.34–35).
- RS232: #set avicustom, #set vsicustom, #set avidisable, #set vsidisable on/off (p.51–52).
What it is
InfoFrames are HDMI data packets that describe aspects of the active signal. VSIF is a Vendor Specific InfoFrame used for vendor-defined signalling.
Why it matters
HDMI behaviour is determined by the complete signal chain. Vertex exposes and manages these technical layers so mixed sources, displays, projectors and AV processors can be configured more deliberately instead of relying only on automatic handshakes.
Common questions
What InfoFrames can the Vertex work with?
It can capture, edit, block or replace HDR metadata, AVI and VSIF InfoFrames, and read SPD, Audio, HDMI Vendor and HDMI Forum InfoFrames (p.110).
What does the AVI InfoFrame do?
It tells the display things like the colour format and colorimetry. With a custom AVI you can, for example, switch a TV into BT2020 mode when the content does not signal it (p.34).
Should I switch off VSIF to fix a problem?
Only for testing. Dolby Vision signalling travels in vendor-specific InfoFrames, so blocking or replacing VSI can break Dolby Vision detection; for normal use leave 'Disable VSI' and 'Enable Custom VSI' off (p.35).
